I like the old Firefox new tab page. It was clean and offered some basic links with an uncluttered appearance using your favorite search engine. Firefox removed this feature with Firefox version 41. Well a young developer brought it back with the "New Tab Override" add-on. Below is the traditional new tab page along with a link where to get this add-on. Enjoy.
